Centene Prior Authorization
Overview
Centene is the largest Medicaid managed care operator in the United States, managing plans across 45+ states through subsidiaries including WellCare, Ambetter, and Sunshine Health. Centene operates distinct prior authorization processes by state plan, requiring providers to verify the specific subsidiary and state requirements. Standard authorizations are approved within 1-5 business days; expedited requests receive approval within 24 hours. Incomplete submissions delay processing and increase claim denial risk.
Key Requirements
- Verify Subsidiary: Centene operates through multiple brands: WellCare (traditional Medicaid), Ambetter (ACA marketplace), and Sunshine Health (Florida). Identify the specific subsidiary from the member's ID card or eligibility system.
- State-Specific Rules: Each state's Medicaid program defines authorization requirements. Verify requirements with your state's Medicaid agency or Centene's provider portal.
- Authorization Requirement Services: Specialty referrals, imaging (MRI, CT, PET), inpatient admissions, certain surgeries, and durable medical equipment typically require pre-approval. Confirm list with your state plan.
- Documentation Standards: Submit diagnosis codes, procedure codes, treatment plan, medical necessity justification, and any prior diagnostic results supporting the request.
Approval Timeline & Process
Centene processes standard prior authorization requests within 1-5 business days. Urgent requests (medically necessary, same-day or next-day approval needed) receive 24-hour turnaround. Expedited requests require documented clinical urgency. Submission methods vary by state: most Centene subsidiaries accept online portal submissions for contracted providers; non-contracted providers submit by phone or mail. Check your state's Medicaid provider manual for specific Centene submission procedures.
